  • This example method includes a step that provides for receiving a thermally conductive material into a chamber (step 5). Once the thermally conductive material is received in the chamber, an additional step is included for receiving part of an optical scope through an orifice, wherein the orifice provides access to the chamber (step 10). It should be appreciated that, according to this example method, this step is accomplished once a tip-portion of the optical scope makes contact with the thermally conductive material disposed within the chamber.
  • An additional included step provides for sealing around the perimeter of the tip portion of the optical scope (step 15). It should be appreciated that sealing around the perimeter of the tip-portion of the optical scope substantially prevents the loss of thermally conductive material from the chamber through the orifice.

  • Fig. 2 is a flow diagram that depicts alternative example methods for receiving a thermally conductive material into a chamber. It should be appreciated that, according to one alternative example method, an included step provides for receiving sterile water into the chamber (step 25).

Accordingly, one alternative example method further includes a step for monitoring the temperature of the thermally conductive material proximate, or near to the optical scope (step 55).

  • This alternative example method further includes a step for storing a battery in a battery compartment (step 90); breaking a cover retention element included on a cover intended to cover the battery compartment (step 100) when the cover is removed (step 95); and removing the battery from the compartment (step 105).

  • Fig. 10 is a flow diagram that depicts one alternative example method for impeding dissemination of fluid from the orifice when a tip-portion of the optical scope is withdrawn from the chamber.

  • Fig. 11 is a flow diagram that depicts one alternative example method that further provides for point-of-use decontamination of surgical instruments. It should be appreciated that, in order to more effectively sterilize surgical instruments after use in the surgical theater, it is advantageous to maintain the tip-portion of any instrument moist. Accordingly, this alternative example method provides an included additional step for receiving into the chamber part of a contaminated surgical instrument into the chamber through the orifice in order to make contact with the thermally conductive material contained therein (step 140). According to yet another alternative method, an additional included step provides for the continued application of heat to the thermally conductive material (step 145).
